"Steven Gerrard is the stand-out captain, and that's not a biased verdict," Carragher told the club's official website.
"He's been the captain of Liverpool for probably a decade. He's captained in Champions League finals, Europe, big Premier League games.
"He's also captained England in the last World Cup and he's one of England's best players. For me, I don't think there's a debate.
"It should be Steven Gerrard without a shadow of a doubt."
